He is believes that blood types are the most important thing when it comes to our health and well-being and that some food can be harmful for one blood type but helpful for other. Also, he claims that even the way you exercise can be closely connected with your blood type, or on the other side, your blood type can cause you some illness.

Some experts disagree with this method of nutrition, but since his book was published, the more than 7 million sold copies worldwide speak for themselves.

How Does the Blood Type Diets Works?

D’Adamo’s theory says that each person has its responses to food, which are closely connected with our blood type. He says that lectins (carbohydrate-binding proteins) can correspond to different blood type in a different way. It can be extremely dangerous on your health if certain lectins get in contact with certain blood type.

Dr. D’Adamo closely explains these side-effects and changes in his book, but, his main goal is to analyze which foods are appropriate for each blood type and the amount in which they should be consumed.

The Four Basic Blood Types:

1. BLOOD TYPE A:

Twenty thousand years ago, when agriculture was developing, this blood type had the change of a lifetime. This means that people with blood type A should concentrate on living a vegetarian way of life – this people are also known as “the agrarians”.

2. BLOOD TYPE 0:

Because it’s one of the oldest blood types, dating from more than 30 000 years ago, it requires a protein-filled nutrition, unlike any of the other blood types. The people that are blood type 0 are also known as “the hunters”.

3. BLOOD TYPE B:

The people from this blood type are known as “the nomads” because they possess the quality to be quite adaptable to dairy products and have the most versatile digestive system of all. It first appeared ten thousand years ago.

4. BLOOD TYPE AB:

Since this is the newest blood type, their diet varies between Blood type B and A. Because this blood type is just a thousand years old, the people are called “the enigmas”.

If you do not know your blood type, it can easily be determined for you by your medic or physician.
